Batch PIN Generator

Used by developers, writers, and creators worldwide.

A batch PIN generator saves real time when you need dozens of codes at once — not one at a time. Set the count (up to 10 by default, adjustable), choose a length from 4 to 12 digits, and toggle duplicate checking on or off. The output copies cleanly into a spreadsheet, CSV, or database import. Four-digit PINs cover 10,000 combinations, fine for locker assignments. Step up to six digits and you get 1,000,000 — the baseline most security-aware apps require. The uniqueness toggle prevents two users receiving identical codes, which matters for ticket systems, access cards, and account provisioning.

Use Cases

  • •Assigning unique locker PINs to a new school-year intake of 80 students
  • •Seeding a Postgres staging database with realistic 6-digit user PINs for load testing
  • •Generating raffle ticket codes for a fundraising event and exporting to Google Sheets
  • •Provisioning one-time access codes for a coworking space door-lock system
  • •Bulk-creating temporary badge PINs for a multi-day conference check-in table

Tips

  • →When pasting into Excel, pre-format the destination column as 'Text' to prevent leading zeros from being dropped silently.
  • →For event ticketing, generate 10-15% more PINs than you need to have spares for reprints or replacements.
  • →If you need PINs in a specific format like XX-XXXX, generate them here then use a spreadsheet formula to insert the separator.
  • →For load testing login systems, generate a batch with uniqueness off to simulate realistic traffic including repeated attempts.
  • →Shorter PINs (3-4 digits) work well for temporary codes that expire quickly; use 8+ digits for anything that persists longer than a session.
  • →Cross-check across multiple generated batches using a spreadsheet's duplicate-detection feature if you're building a large master list over several sessions.

FAQ

how do i generate unique PINs in bulk without duplicates

Set the 'Ensure unique PINs' toggle to yes before generating. The tool checks each code against the rest of the batch and replaces any repeat before it reaches the output. For extra safety across multiple batches, paste all lists into a spreadsheet and run a duplicate-check formula.

what PIN length is actually secure enough for user accounts

Four-digit PINs have only 10,000 possible values — fine for lockers but weak for accounts. Use at least 6 digits (1,000,000 combinations) for user authentication, and 8 digits for anything payment-adjacent. Most modern EMV card environments already mandate 6-digit PINs.

can PINs with leading zeros cause problems when pasting into Excel

Yes — Excel silently strips leading zeros if the column is formatted as a number. Format the target column as Text before pasting, or prefix each value with an apostrophe to force text treatment. Alternatively, import via CSV with the column type set to text in the import wizard.
